I’ve been making more homemade baby foods for John. With all three items (sweet potatoes, carrots and pears), I just boiled them in water, drained most of the water (saving some for thinning the puree as necessary), and zapped them in the food processor. I put them in ice cube trays, froze them, and later placed the cubes in freezer bags. I take out as many cubes as necessary for each of John’s meals.
